CONNECTION FOR WIRES OR CO'NDUCTORS.

Specification of Letters Patent.

Patented Jan. 25, 1910.

Application filed March 23, 190.). Serial No. 485,352.

1 '0 all whom it may concern:

Be it known that I, .llnwnnn Sturatmilna,

a subject of the German Empire, residing at Nuren'iberg, in the county of Ivlittlefranlqen, State of .liavaria, Germany, have invented certain new and useful. .lml)rovements in Connectors for tires or Conductors, of which the following is a specification.

The purpose of my invention to reduce the length requisite in incased twisted joints.

It further consists of other novel features of construction, all as will be hereinafter fully set forth.

Figure 1 is a plan. view of a casing in place but not twisted. Fig. 2 is a plan view of a casing after it is twisted. Fig. 8 is a cross section upon line .e zv, Fig. .t is a cross section upon line :I/--|7/ Fig. 1.

Similar numerals of reference indicate corresponding parts in the figures.

Referring to the drawings, ft designates a tube having flat sides 2 joined by curved edges 3 and of su'tlicient size to accommodate two wires of diameter equal to the distance between the inner faces of the flat sides. At each end I reduce the size of the opening below that of the cross section indicated and as shown in Fig. at by forming an end. wall 4t and extension 5, said extension with the pot tion 6 of the adjoining edge 3 forming a nipple having interior diameter equal to that of the wires 7 and 8 intended to be passed within the tube. The nipples thus formed at the two ends are staggered, one adjoining one edge and the other the other edge of the tube in such a manner that the wires inserted through these nipples lie side by side Within the tube, in order that they may make contact within the same. The wires thus inserted can each extend the entire length. of the tube and abut against the closing wall 4 of the opposite end of the tube or these wires can be inserted throughout a portion only of this lengtln Complete insertion is desirable because the twisting hereinafter referred to can then be made E uniform and continuous throughout the en tire length ol the tube.

It is deemed important that the interior cross area 0] the llatlcned lube in its normal condition be greater than the combined diameters of the two wires as seen in Fig. l, so that when twisted the material of the tube will be depressed in between the wires as seen in Fig. i, and the wires thus brought substantially in contact with each other, and the inwardly depressed portions of the tube serve to hold the wires rigidly in fixed position. The wires as thus inserted are twisted to con'iplete the contact; between the wires themselves and of each wire with the adjoining interior surface of the tube throughout as large an area as possible. I thus secure not only as complete initial contact as previously obtained but protect against cor rosion due to the elements by means of the close lit at each end between the nipple and the entering wire.

Having thus described my invention, what I. claim as new and desire to secure by Letters Patent, is:

1. In a device of the character stated, a guide tube to receive two wires and a circular nipple extending longitiulinally from the tube at one side of each end, the nipples being staggered to be in line with different wires, the n'ialerial ol the tube being formed into a closure for the remaining portion of the tube in proximity to each nipple.

2. In a device of the character stated, a flattened tube, a circular nipple extending longitiulinally from the tube in line with a portion of each end, and an abrupt stop closing the remaining portion of the tube adjacent the nipple at. each end, the nipples and stops at the two ends being staggered respectively to place them adjacent differentpor tions of the flattened section.
